ELEVATO R.

SPECIFICATION forming part Aof Letters Patent No. 237,815,`dated February 15, 1881.

Application filed June 10, 1880.

provide a device of this character which shall be of simple construction, of convenient and safe operation, and having new and improved appliancesffor hoisting and stopping the car, for signaling, for the prevention of violent shocks to the car at the upper and lower terminus ofthe car-track, and for keeping the hand-rope, through which the car is operated, at all times taut.

With this end in view my invention consists inthe combination, with a hand-rope wheel, of a pair of sheave-frame brakes adapted to govern the movements of said wheel.

My invention further consists in the combination, with a hand-rope wheel, of a pair of sheave-frame brakes and a lever, arms, and hangers by means whereof the brakes are made to act in unison.

My invention further consists in the combination, with a hand-rope wheel and a hoistwheel connected therewith, of a pair of sheaveframe brakes and a lever, arms, and hangers by means whereof the brakes are made to act in unison.

My invention further consists in the combination, with an elevator-car, of a hoist-rope attached to the top of the car, and passing over the hoist-wheel and apivotal pulley-block, whereby the counterpoiseweight is adapted to be operated in either a side or back pocket provided therefor.

My inventionfnrther consists in the combination, with the hand-rope, of devices to keep the said rope taut, consisting, essentially, of two vertical guideways located at the bottom of each side of the elevator-frame and weighted sheave-frames having free vertical movement (No model.)

in said guideways, the hand-rope running un der the pulley in said sheave-frames.

' My invention further consists in the combination, with a car, of a bell located in said car, and trips located in the elevator-frame and adapted to sound the bell.

My invention further consists in the combination, with the elevatorcar and elevatorframe, of springs and plates disposed to form a resilient bed at the upper and lower terminus of the car-track.

My invention further consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front view of my improved dumb-waiter or elevator. Fig. 2 is a view,inlongitudinal crossi section, thereof. Fig. 3 is a plan View. Figzi is a view of the signaling device with the bell removed. Fig. 5 is a rear view thereof. Fig. 6 is a view of the pivotal block over which the hoistrope runs. Fig. 7 is a side view of a trip mounted in its plate. Fig. 8 is an end view of the elevator-car. Fig. 9 is a view of the elevator-frame, in vertical section, and showing the disposition of the trips; and Fig. l() is a view, in detail section, of the signaling device.

LetA represent the elevator frame or case; B, the elevator-car; C, the main wheel; D D, sheave-frames; A', hoist-wheel; G', handro'pe, and Dl elevator-rope passing over hoistwheel A'.

The'main wheel C and hoist-wheel A are mounted on `a shaft, a, having its front and rear ends journaled in the main-wheel frame b and cross-block c.

Sheave-frames D D, located to the right and left of the lower portion of the main wheel C, are hung from the top beam of the main-wheel frame by depending arms rigidly secured to the sheaves, but pivotal] y secured to the top beam of the main-wheel frame, as before mentioned. Each of the sheave-frames has in its front face a groove equal in width to the peripheral width IOO by weights F F, secured to the outer faces of the sheave-frames. The two sheave-frame brakes are made to operate simultaneously by the employment of a coupling device consisting of an equal-armed lever, b', pivotally secured to the upright post c of the frame b.

To the lower arm of the lever b the inner end of a horizontal arm, d, is pivoted, the outer end of which latter is pivoted, at a2, to the lefthand sheave-frame D. Horizontal arm b2 is, in like manner with the arm d', pivoted respectively at its inner and outer extremities to the upper end of lever b', and, at c2, with the lefthand sheave D.

Mounted in the standard d2 of the frame b, and located under the sheaves D D, are two pulleys, A2 A2, grooved to retain the handrope C', by means of which the movements of the waiter-car are controlled. The said rope C is endless, and is secured above and below the two points between which the elevator-car is to traverse. Beginning at the right, the rope passes up through the partition B2 and standard d2, over the outer face ofthe pulleyAz, and onto the inner face of the pulley a ofthe right-hand sheaX-*e-frame D. From thence it passes over the main wheel C and down over the inner face of the pulley a of the left-hand sheave-frame D, thence to the outside face of the pulley A2, mounted on the standard d2, and through the partition B2. The lower portion of the endless rope C runs under two pulleys, C2 C2, mounted in weighted frames DZDZ, which latter have free vertical movement in guideways E E.

Atmospheric changes and other causes will operate to alter the length of the hand-rope, and often cause serious trouble in the manipulation of the car. This objection is done away with by the employment of these verticallymoving weighted sheave-i'rames, which preserve the rope taut when stretched, and automatically adapt themselves to its length when shortened.

Elevator or waiter car B, provided with grooves G, is guided in its upward and downward motion by guides or rails H, which are received in the grooves G, the power whereby the caris raised and lowered being exerted through the rope D', secured to the carin any desired manner, and which passes up through the partition B2, over pulley f, mounted in block G3, situated to the left of the shaft a. From thence it passes from left to right over the hoistwheel A', and down to pulley h, mounted in the inner end of a pivotal block, c, and then over to pulley b4, journaled in the outer end of the said pivotal block, and finally terminates ata counterpoise-weight, g', which has vertical movement in a pocket, h', formed in the side or back of the frame. The object of adapting this block e to be moved is to allow, when more convenient or desirable, the cord or rope D to be received, together with its counterpoise-weight, in a pocket or recess, h', in the back of the elevator frame or case A.

Steel springs f2 are here shown as attached to the lower face of partition B2 and the bottom ot' the car B, said springs engaging with the steel plates g2, respectively secured to the upper end of the car and the upper face ofthe partition hZ ofthe frame A. Ofcourse the arrangement of these steel springs may be changed and still accomplish the object of their design, which is to avoid the shock and consequent damage of the contents of the car when too violently stopped at either of these points.

The signaling device, by means of which the arrival ofthe car at any landing or story is announced, consists of a bell placed in the elevator-car and actuated by a series ot' trips 1ocated in the side of the frame A. Plate E', having two slots, F G, is recessed in the side 0f the car, and has secured to its under side a plate, H5, arranged to have a sliding movement on the pivot E2 by means of the slot F2. To the outer end of the said plate H5 a knob or handle, G2, is secured, which projects through the slot F of plate E. A post, g4, secured to the inner end of plate H5, and projecting through aperture G in the rear end ot' plate E, is provided with a bell, H2, which is sounded by a hammer, a3, pivoted in plate H5, actuated by a spring, b3, and operated to strike the bell by means of adepending foot, c3, which engages with the trips da, secured to the side of the elevator-frame. Said trips d3 are mounted on plates c3, recessed in the side of the elevator-frame, are held in their normal position at right angles with the plate c3 by springs f3, and may be depressed by any force actingfrom above, but do not yield to any force acting on their under faces. It is thus apparent that in the downward trip ofthe elevator-car the depending foot c3 will depress the trips without sounding the gong; but in the upward trip of the car the depending foot c3 of the bell-harnmer will engage with the trips d3, the force of the spring b3 will be overcome, and the hammer a3 will recoil. As soon, now, as the engagement between the trip d3 and bell-foot ci is released, the hammer, influenced by the spring b3, will ily back to its former position, and in so doing strike the bell. The trips are not arranged in line, but a trip at one iioor is out of line with every other tripin the elevatorframe. The object of this arrangement is to enable the bell to be sounded only at the place where the car is destined to stop, and not at every trip between that point and the starting-point of the elevator.

The plate H5, secured, as before described, to the under side of plate e', has longitudinal 'movement in the slot F2, and is moved, to-

gether with bell H2 and its depending foot c3, by means of knob G2, projecting through slot Ff.

Any arbitrarily selected set of symbols placed at different points of slot F/ designate different trips located at certain landings. For instance, let us suppose that by drawing the knob G2 to the eXtreme forward portion of slot F the foot c3 will be placed in position IOO IIO

the starting-point.

to engage with the trip at the first story of landing and there sound the bell. Again, suppose we push the knob to the extreme inner endof the slotF. Now the foot c3 will be placed in position to engage trip cl3 at the fourth story and there sound the gong', escaping all trips between the trip at the fourth story and It will be thus seen that I am enabled to sound the bell only at the story or landing where the car is destined to stop, and the signaling device may be set at any story to sound at stories above.

Having thus fully described the operation ofthe signaling devices used with my elevator or dumb-waiter, I will proceed to describe the operation of the car, which is effected by means of the hand-rope C. As has been stated, the hand-rope C passes over the outside faces of the pulleys in the standard d2 and over the inside faces ofthe pulleys a', journaled in the sheave-frames D D. It will thus follow that when the ri ght-hand portion of rope U ispulled down it will tend to straighten, and in so doing will lit't the'right-hand sheave from engagement with the periphery of the wheel A, and also simultaneously lift, through the lever and arms d b b2, the left-hand sheave from engagement with wheel A, which latter, now released from the sheaves or brakes, will be free to be revolved by the rope from left to right and the waiter-car will be raised as long as the rope is pulled upon; but the moment the operator stops pulling on the rope the sheaveframes will fall and lock the main wheel again by the attrition between the periphery of the main wheel and the inner faces of the sheaveframe brakes. To lower the elevator-car the left-hand rope may be operated in the same manner as the right-hand one, the only difference in the effect being to revolve the wheel A from right to left instead of from left to right.

rEhe advantages of my improvedV dumbwaiter are manifold: Its construction is simple and its operation is easily controlled the brakes, being of automatic operation, are entirely independent of the hand-ropes, which latter, if broken or worn, can be easily replaced, and the signaling devices will be found to be of great advantage and utility.
